The Ministry of New and Renewable Energy (MNRE) has issued a fresh notification extending the self-certification of solar photovoltaic (PV) inverters under the Bureau of Indian Standards (BIS) from December 31, 2021, to June 30, 2022. The extension was granted as the industry had sought more time for compliance, considering the issues relating to testing and the level of preparation of test labs.


However, the deadline is subject to the condition that manufacturers have valid International Electrotechnical Commission (IEC) accreditation and test reports from international test labs for the smooth implementation of the order.

Earlier, the Solar Energy Federation, Power Products Manufacturers and Traders Association, and Industries had conveyed to the Ministry the difficulties relating to certification due to the Covid-19 pandemic, high testing fee, and limited testing facilities for testing up to 150 kW capacity inverters and had sought more time for compliance.
